1: Jill and I were having that angry make up sex when I decided to give her a thunder schlap that would wake the neighbors.

2: My ex-girlfriend in college once invited me into her dorm room to have a threesome with her roommate Sarah. It was only then that I discovered she merely wanted to utilize my schlong as a double handed weapon for schlaping Sarah across her face.

3: Executing the thunder shclap is illegal in the state of Utah and or any other area in the USA that contains a large presence of Mormons. Failure to comply with this regulatory policy could lead to a fine of up to $250 and up to 6 months in the county jail.
